What was the front wall of the trench call World War 1?

The front wall of the trench during World War I was commonly referred to as the "parapet." This structure was typically reinforced with sandbags, soil, and barbed wire to provide protection for soldiers from enemy fire. The parapet allowed troops to fire their weapons while minimizing exposure to incoming artillery and small arms fire. Additionally, the design of the trench system included features like firing steps and observation posts to enhance defensive capabilities.
